Streetdirectory.com HDB Senja is located at Bukit Panjang, a residential district in northwest Singapore. This area would resemble a concrete jungle if not for the several small parks that were developed by the Singapore URA board for the residents’ leisure and fitness use. Another form of exercise – shopping! - can also be done at the shopping malls here. Bukit Panjang Plaza offers several channels for those with hobbies and interest at its Super Bowl, art and craft supplies store, Comics Connection and the game arcade.
